Subject: [PATCH] src/nl_extras.h: fix compatibility with libnl 3.3.0
|
||
|
|
|
||
|
|
nl_extras.h defines a set of nla_set_s*() functions if not provided by
|
||
|
|
libnl. They are provided by libnl since version 3.2.26. The test
|
||
|
|
(LIBNL_VER_MIC <= 26) was working fine while libnl was in the 3.2.x
|
||
|
|
series, but now that they have incremented the minor version, the
|
||
|
|
micro version was reset to 0, with the latest libnl version being
|
||
|
|
3.3.0.
|
||
|
|
|
||
|
|
Due to this, the condition (LIBNL_VER_MIC <= 26) is true, and we get
|
||
|
|
redefinition errors because nl_extras.h redefines functions already
|
||
|
|
provided by libnl.
|
||
|
|
|
||
|
|
This commit improves the condition so that nl_extras.h provides the
|
||
|
|
missing functions only if the minor version is < 2, or if minor is 2
|
||
|
|
and micro is < 26.
